What Is Bacteriostatic Water for Injection?

Bacteriostatic Water for Injection, USP, is a sterile, preservative-containing aqueous solution designed exclusively for parenteral use. Each 30ml vial contains purified water and 0.9% (9 mg/mL) benzyl alcohol, which acts as an antimicrobial preservative to inhibit bacterial growth.​

Unlike standard sterile water, the benzyl alcohol preservative allows the vial to be accessed multiple times without compromising sterility, making it ideal for multi-dose clinical protocols and high-frequency medication preparation workflows.​

The solution has a pH range of 4.5 to 7.0 (typically 5.7) and is chemically designated H₂O, meeting all USP pharmacopoeial standards for injectable preparations.​

What Is Bacteriostatic Water for Injection Used For?

Bacteriostatic Water for Injection is indicated for diluting or dissolving drugs intended for intravenous (IV), intramuscular (IM), or subcutaneous (SubQ) injection. It is widely used across several medical and clinical settings, including:​

• Medication Reconstitution — dissolving lyophilized (freeze-dried) drugs such as antibiotics, biologics, and peptides before administration​

• Drug Dilution — reducing the concentration of medications to the correct dosage for injection​

• Hormone Therapy Preparation — commonly used in HRT, HGH, and testosterone preparation protocols​

• Peptide Reconstitution — a preferred diluent for research-grade peptides that require aqueous reconstitution​

• Compounding Pharmacy Applications — used in compounding environments where repeated vial access is necessary​

⚠️ Important: Bacteriostatic Water for Injection should not be used for newborns or in patients with known sensitivity to benzyl alcohol. Always follow professional medical guidance.​

Why Choose the 30ml Vial Size?

The 30ml vial is the most popular size for clinical and professional settings because it strikes the perfect balance between volume and sterility longevity. It offers enough solution for multiple reconstitutions from a single vial while minimizing waste.​

For high-volume facilities, the 30ml vial is also available in bulk packs (25-pack, 100-pack), providing a cost-efficient and reliable supply chain solution without compromising product integrity. Single vials are equally practical for individual practitioners or those managing smaller patient loads.​

How to Use Bacteriostatic Water for Injection Safely

1. Inspect the vial before use — ensure it is clear, free of particles, and the seal is intact

2. Use aseptic technique — clean the rubber stopper with an alcohol swab before each withdrawal

3. Use a sterile syringe and needle for every draw

4. Store at room temperature (20°C–25°C / 68°F–77°F), away from direct light

5. Discard unused portions after 28 days of first access, or per your facility’s protocol​

6. Do not freeze — freezing may compromise vial integrity and preservative efficacy
